Product Details

Product Applications

AMSOIL OE Synthetic Motor Oils are excellent for use in all types of gasoline-fueled vehicles. They are recommended for all domestic and foreign vehicles requiring any of the listed performance specifications:

Product Application Specs

Product Description

OE Synthetic Motor Oil provides excellent wear control and protects critical engine parts like pistons and cams. This added protection is particularly important in the extreme environments produced by today's smaller displacement engines that often run lower viscosity oil. Camshaft wear can result in poor valve timing, greatly reducing engine efficiency and leading to expensive repairs.

Protects Pistons from Low-Speed Pre-Ignition

OE Synthetic Motor Oil features unique chemistry proven to protect your engine against the harmful effects of low-speed pre-ignition (LSPI). LSPI is the spontaneous ignition of the fuel/air mixture prior to spark-triggered ignition. Most new engines feature gasoline direct injection (GDI), often coupled with a turbocharger. These technologies heighten the possibility of LSPI events, which can destroy pistons and connecting rods. A properly formulated motor oil is critical for protecting your engine against LSPI.

Original equipment manufacturers (OEMs) like GM have addressed the issue by designing tests to determine a motor oil's ability to prevent LSPI. OE Synthetic Motor Oil achieved 100 percent protection against LSPI2 in the engine test required by the GM dexos1 Gen 2 specification - zero occurrences were recorded throughout five consecutive tests.

1 Based on independent testing of OE 0W-20 in the Peugeot TU3M Wear Test as required by the dexos1 Gen 2 specification.

2 Based on zero LSPI events in five consecutive tests of AMSOIL OE 5W-30 Motor Oil in the LSPI engine test required by the GM dexos1 Gen 2 specification.

Improves Fuel Economy & Maintains Low Emissions

OE Synthetic Motor Oil is licensed by the American Petroleum Institute (API) to meet and exceed the requirements commonly found in owner's manuals. It excels in fuel-economy testing, earning the additional "Resource Conserving" designation from the API. OE is also friendly toward modern emissions-control systems, promoting proper operation of catalytic converters for optimum service life and low exhaust emissions.

COMPATIBILITY

AMSOIL OE Synthetic Motor Oil is compatible with other synthetic and conventional motor oils. Adding other oils, however, will shorten the life expectancy of AMSOIL motor oils and reduce their performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.

Aftermarket oil additives are not recommended for use with AMSOIL OE Synthetic Motor Oil.

SERVICE LIFE

In gasoline-fueled vehicles, AMSOIL OE Synthetic Motor Oil is recommended for the intervals stated by the vehicle manufacturer or indicated by the oil life monitoring system. Change oil filter at every oil change.

HEALTH & SAFETY

This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

Trusted

I've been using Amsoil for around 6 years now and I've never had a complaint about their oils or their customer support. I use their oils in 2 Harley's, 2 Ram trucks (gas and diesel) and 1 Jeep and couldn't be happier with how smooth they all run and the level of great customer service I get when placing the orders.

I honestly believe all oils are good, but I feel that Amsoil is the best - hands down. Vehicles are expensive to replace, so even the best oil, whatever you think it is, is cheap insurance.

Amsoil always holds up.

I am not a chemist or engineer, so I cannot speak as to what's inside the bottle. However I am a mechanic and can speak as to what's inside a engine, transmission or differential. I've used Amsoil on and off over the years alone with other bands of synthetic and conventional oils. I've never used anything that didn't work. However, I've found good oils last longer. Being a fleet mechanic I change a lot of oil and get to see what it looks like under abuse. Amsoil always holds up. That's why I use it.

OE is the best choice for me.

I had always purchased the top-line signature-series for my cars and trucks in order to take advantage of their long drain intervals.

Recently I bought a new midsize truck with a V6 engine. The dealer offers a free one-million-mile powertrain warranty to the first owner. Owner must follow the factory-recommended service intervals; oil drain and filter come every 5,000 miles.

I went with OE because it has to be drained so often, but would it provide about the same protection and mileage as the SS? Before OE the mileage average was 23.4 mpg. After 5,000 miles on OE the mileage average is 24.3, an increase of about 9%. The engine is very quiet at idle and runs very strong. No oil seeping anywhere.

Very particular about everything, Watch for new leaks, old seeps, consumption, color, smell, everything. Tahoe has 80,000 miles, PU has 60,000 miles. Tahoe has had a slight seepage around rear main area and also had started using a quart of oil in 3,800 miles after every oil change at about 30,000 miles. Since switching to AMSOIL, seepage has just about completely stopped, and consumption has slowed to approx. 1/2 quart at 3,800 miles after about a year and a half of usage and 3 oil changes at 4,000 miles. Hoping for continued improvement with time and miles. PU has never used a drop or leaked a drop between changes. Have always used Valvoline products prior to trying AMSOIL. Still watching results and hoping for the best. Also put 50 wt. SYN. AMSOIL in my '80 diesel truck transmission and saw easier, faster shifting, and less noise. No leaks.
